Problem 7: Consider the following model of a person lifting a weight (W2=225N) and having straight legs. The person is standing still. The trunk of a person weights W1=320N. Additionally it is known that AE=1/2AB and AD=2/3AB. Calculate tension T and a total force F acting on point A as a function of the angle a (as indicated on the figure on the right). If the angle a becomes very small, do these two forces become larger or smaller? Now assume that the cross-sectional area at point A has a radius of r=4cm. If the vertebrae L5 fails under a compressive stress of 1.7 x 108 m2, how much additional longitudinal force is required to cause the vertebrae to fail under compression? 00 T 10000 D a W2 E А 30° w = weight of body trunk (320 N) W, weight of arms and head plus 225 N (382) A = rigid fulcrum at about fifth lumbar vertebra 1Bhoom (body trunk) TD cable representing effective muscle AD 2/3 AB AE 1/2 AB T = tension in the muscle 225 N (a) a)
